revolution of the engine is used to increase `the speed of the engine, the suction of air is increased, andthe supply of gasolene must corres ondinglyl `increased.-` My invention 6o provi es a means of automatic lregulation and supply of gasolene for such emergency. The lrasolene-reservoir 9 is of a double functiona use and benet--rst,byreason of its contiguity to the heated Water-jacket to 65 warm the gasolene, and, second, to afford an immediate extra suppl of heated gasolene to t furnish a reserve for t 1e motor at any extra revolution. It `will be understood in this connection that the needle-valve 12 ordinaril 7o controls the supply of gasolene and is se't with the ointer 13 indicating upon the dial 14 the degree of supply. The reservoir or chamber 9 is regarded as an important feature of my invention, 4as it 75 affords a means for heating the gasolene before vaporization and also affords an extra supply of gasolene for an increased revolu# tion of the motor. y

Inv the operation of the motor the air is 8o sucked into the carbureter through the inleti pipe 11. The gasolene is supplied from the r chamber 9 through the channel 16 and around the needleoint 12 and upwardly through the charme 17 into the vaporizing-chamber 85 18, where it is mixed With the air,'and the vapor passes through thevapor-outlet 15 into the engine. 4 19 represents a valve normally resting on the valve-seat 20 bygravitation. When the 9o gasolene lssupphed and the motorstarted,

the pressure ralsesthe valve 19 in the stem 21 sufficientlyV to `,admit the asolene into the vapmixing-chamber, and when the ressure and suction, arefsto'p )ed the valve c rops by g5 gravitation toshut o the supply of O'asolene.

24 represents a primer that, before starting the engine, may" be? pushed against the incline 23 Ito raise thevalve 19 and fadlnit a small supply of gasolene, which then drops into the prnner-cup 25. When the suction 1s started, the air is drawn through the inlet 11, around the cup 25 and the cross-pipe 26, breaking and staggering thefcurrent of? air and forming apvortex inthe center, which 'materially assists the process "'zat'on "`"ihe"gasd-y lene is `drawnfr Erinto the pente!" ofl'thecurrent r edi ely f y l rizdi "t Having thus described my invention, what I claim to have invented, and desire tosecure by.
